Geochemical Characteristics of Mesozoic Petroleum Systems in the Bonaparte Basin

Geoscience Australia Data presents isotopic and biomarker analyses of Mesozoic oils from the Bonaparte Basin, northwestern Australia. The study characterizes multiple oil families within the Westralian Petroleum Supersystem, correlating oils across sub-basins and identifying distinct geochemical signatures. This research was presented at the 2000 AAPG International Conference and Exhibition in Bali.

Use Cases

• Correlating oil families across sub-basins based on isotopic and biomarker data mentioned in the description
• Identifying source rock characteristics for Jurassic and Early Cretaceous rocks based on geochemical signatures
• Distinguishing between marine and land-plant influenced oil families based on biomarker analysis
• Contrasting Mesozoic petroleum systems with Palaeozoic systems in the Petrel Sub-basin

Strengths

• Analysis is based on isotopic and biomarker data, which are standard geochemical characterization methods
• Study identifies and contrasts four distinct oil families/sub-families with different geochemical signatures
• Data is sourced from Geoscience Australia Data, a government geological survey organization

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data may reflect geographic bias inherent to the specific basins studied
